The article presents results of research on drying a slurry consisting of distilled water and finely chopped cooked chicken protein of table eggs. The suspension is placed in a Memmert oven, which has temperature of 60 °C. In the process of removing moisture when drying the slurry of water - boiled protein we examined kinetics of its drying and performed chronological photographing of conformation of the system of water - boiled protein. The final weight of the protein remaining after evaporation, was 0.06 g corresponding to 26% by weight of cooked protein source in an amount of 0.23 g. The analysis of the system appearance including the evaporation of the water showed that the protein was originally white, and this color does not undergo any changes until 35 minutes of drying, i.e. when the main base is water. Upon further drying of the suspension, starting with 40 minutes, boiled protein literally "melts" in the surrounding water residues; and as it is disappearing, becoming more and more transparent. Meanwhile, the forms of the protein are becoming round and transforming into the form of liquid crystals. The final phase of the protein is a solid transparent film

Groundwater is the source of drinking water in rural areas, it is a part of urban water and it is formed due to the filtering of cross waters in a stratified medium permeable rocks. The impact of anthropogenic factors leads to changes in the qualitative composition of groundwater. The article presents the results of industrial environmental monitoring of ground water refinery of Tuapse in the period from 2012 to 2016 according to its content of ammonium-nitrogen, nitrate-ions, sulphates, formaldehyde, toluene, xylene and ethylbenzene. Analysis of groundwater sampled from wells located at the site of the refinery was conducted by a factory-certified laboratory. The content of the components meet the regulatory indicators. We examine the effects of industrial toxicants on the human body

After silage of ash captured by the electrostatic precipitator, we installed the cyclone of NIIOGAZ CN-15-500 for exhaust gas pre-treatment of the ash resulting from the process of burning solid fuels (coal of Donetsk) in boilers of Novocherkassk hydro power plant. The plant cyclone examination was performed in a production environment of Novocherkassk hydro power station comprising 4 cylindrical cyclone element diameters of 500 mm, and is defined by its real effectiveness, which amounted to 91%. After the cyclone, the gas enters the two-bag filter FRKI-90KP3-2-2 designed to trap solid ash residues and installed over the silo dry ash. Filters are manufactured in climatic design for temperate and cold climate with the accommodation category 4. The article shows the characteristic of the test results and bag filters FRKI- 90K-P3-2-2 before and after the cyclone in the cleaning system. The work presents the analysis of the composition of the ash and compares it with published data. It is experimentally proved that the inclusion of Cyclone CN-15-500 in the process diverting gas purification scheme allowed more efficient operation of fabric filters, reducing the dust significantly for the input gases

The electric method of gas dedusting is the most effective, since it allows capturing solid particles with a size from 0.01 µm to tens of microns. The efficiency of dust and gas cleaning equipment of Novocherkassk SDPP for cleaning flue gases from ash at power units 1-7 in the period from February 2015 to February 2017 is considered. The main equipment is electrostatic precipitators. As a solid fuel, Donetsk culm is used. It is established that the efficiency of waste gas purification at power units 5-7 was about 99 %, while at power units from the 1st to the 4th this value was within 95-96 %. The data obtained correspond to the design data, but it is recommended that the cleaning devices be improved to improve their efficiency. The most acceptable is a combined electrofilter-bag filter
